WIRELESS LIGHTING SYSTEM.

To all 'whom 'it may concern.

Be it known that I, EDWARD B. TUSTIN, Jr., citizen of the United States, residing at Bloomsburg, in the county of Columbia and 5 State of Pennsylvania, have invented certain new and useful .Improvements in Wireless Lighting Systems, of which the following is a specification. K

The present invention rovides novel means for lighting'a series ofp lamps at about the same time without requirin them to be in the same circuit, or electrica ly connected by Wire. L

The invention is of especial advantage in rural districts, or sparsel settled sections, or Wherever a number o widely separated lights are required to be lighted at or nearly the same instant -and it is not feasible, or practicable, to include them in one circuit.

The purpose of the invention is -to devise novel means forusing Hertzian waves as the means for .effecting the results aforesaid, said waves being sent out from a given station, and each lighting system including means capable of being affected by such electro-motive waves to effect -illumination of the lamps forming a part thereof.

'The invention consists of the novel system and arr/angement of parts subst-antially as shown in the accompanying drawing, which is a diagrammatic view.

The antenna circuit includes the coherer 1 and a` tapper 2 is arranged to coperate with said coherer to loosen the particles after the surges produced by the Hertzian waves. A relay 3 included in a local circuit, is energized when the coherer is affected by the electro-motive waves striking the antenna `so as to close a local circuit and produce the desired effect. The relay 3 is' located in a i local circuit containin battery 4, a wire 5 connecting one pole o said battery to the ground wlre 6 of the antenna circuit, the other pole of the battery having connection with the antenna 7 by means of wire 8, which latter also includes an inductance 9 to prevent the surges affecting the relay 3. A capacity sleeve.10 is tted around the inductance'9 and is connected by wire 11 to the ground wire 6 of the antenna circuit, and

supplements the action of the inductancey in preventing the surges set up in theantenna circuit from affecting the relay 3 and interfering with the functions normally performed thereby in the system.y

The tapper circuit includes wires 12 and Specication of Letters Patent. Patented June 21, 1910, Applicationniea April 1, 190s. serial No. 424,6ns.

13 and elements of a battery 14, and this circuit is closed by the relay 3 when energized by the action of the Hertzian or elecelement of the battery by means of a wire .15 and the circuit closing contact and armature of the relay 3.

A local circuit closer for the lamp circuit includes an electro-magnet 16 and wires 17 and 18, the wire 17 running to one pole of the battery 14 and the wire 18 having connection with the other pole of an element of the battery 14 by means of the wire 15 and the circuit closing contact and armature of the relay. As clearl indicated in the drawing, like elements o the battery 14 are electrically connected to one another and to the wire 15, whereas the opposite elements have electrical connection with, respectively, the tapper and circuit closing circuits. This results in producing in effect two independent circuits, the electro-motive force of one being balanced by the electro-motive force of the other so that the current of the battery 14 is divided and sent through the tapper and circuit closing electro-magnets to energize the same each time the relay 3 is vitalized.

The reason for using what is practically two independent circults with the opposed elements of the battery connected in separate circuits, is that the magnet which operates switch 22 is wound with heavier wire than the magnet which is used in the tapper or de-coherer, therefore the magnet which is wound with the heavier wire consumes more current than those which are wound with a finer wire. Two sets of batteries are used because of the difference of resistance of the two magnets. l

The lamp circuit includes a current generator 19, one or more lamps 20 and a circuit closer, the latter comprising an electro-ma net 21 and armature 22. A switch 231s provided in the lamp circuit to break the same when required. An armature 22 is included in the lamp circuit and is adapted to be attracted by the electro-magnet 16 when vitalized s o as to close the lamp circuit, the latter being maintained in closed relation by the attraction of the electro-magnet 21 after the lamp circuit has been initially closed. v

One wire of the electro-magnet 21 is electhe armature 22 and closes the lamp circuit each electric light system-also has an antenna c1r' trically connectedwith the core forminga vpart of said electro-magnet, whereas the opposite end of the wire is -connected with a lead of 4the lamp circuit.

It is presumed that in rural districts and sparsely settled sections, orwidely separated stations equipped with electric light plants, place or station soA provided with an cuit and appliances as'herein lset. forth so that Hertzran or electro-motive Waves sent out from a given station will produce surges or electrical impulses inthe several antenna circuits, with the result that the lamps are lighted. When the coherer of the antenna circuitis affected, an impulse is produced in the relay 3 suicient to energize the same and close the circuit through the tapper and .through the electro-magnet' I6. When .theA

electro-magnet '16 is energized, it attracts provided the switch 23 has been .previously closed. The current of. the lamp circuit passing through the electro-magnet 21 keeps the same vitallzed and attracts the armature 22 and holds the circuit closed untilv interrupted by the switch 23.

It is to be understood. that the several aparts are situated or so placed as not to be tampered with, hence when the switches of the several lamp circuits are closed, the lam s are lighted at a given time bythe out of Hertzian Waves in the mannerfwel understood, said waves producing electrical impulses or surges in the antenna circuits, with the results vhereinbeiore set forth. Having thus described the invention, what is claimed as-new is:

1. `In combination, a v lighting circuit,

' lamps therein', and an electrical circuit closer for the Alighting circuit included therein, an electro-magnet in said lighting circuit cooperating with said circuitY closer -to hold thesame closed while current is passing in the llghting clrouit, an antenna circuit, a

local circuit includin a relay and having electrical connection w1th the antenna circu1t upon oppos1te sidesof `the coherer, a tapper lclrcult, and a' circuit` closing circuit having a battery and a closer' common to ch, lsaid closer adapted' to be operated by 'th relay,

'and theV circuit closing circuitinclud ng an relay and having an electric connectionl with the antenna circuit lon vopposite sides of the coherer, a tapper circuit, an electro-magnet arranged to closethe circuit closer'of the lamp circuit, a circuit having therein a source ofpower and ccnnected to said-.electro-magnet, a circuit closer in the last named circuit, actuated by said *relay' magnet, an

electro-*magnet in the lam circuit adapted to hold the circuit closer 0E the lamp circuit closed -after itv has been vinitially operated,

and means for cutting oil currentthrough the lamp circuit, thereby demagnetizing said circuit and releasing the circuit closer.
